Statewide Crop Mapping

Land IQ was contracted by DWR to develop a comprehensive and accurate spatial land use database for the 2021 water year [WY 2021]. The primary objective of this effort was to produce a spatial land use database with accuracies exceeding 95% using remote sensing, statistical, and temporal analysis methods. This project is an extension of the 2014, 2016, 2018, 2019, and 2020 land use mapping, which classified over 14 million acres of land into irrigated agriculture and urban areas. Land IQ integrated crop production knowledge with detailed ground truth information and multiple satellite and aerial image resources to conduct remote sensing land use analysis at the field scale. Individual fields (boundaries of homogeneous crop types representing cropped area, rather than legal parcel boundaries) were classified. To account for the frequency and seasonality of multiple-cropped fields, peak growth dates were determined for annual crops.
